The Solar Box Cooker is a design at this time focused almost entirely on home built, low cost, low skill cookers that can be pulled together from materials often available within the home in the U.S. or surely within the closest shopping center. Although they reach 275 F. to 300 F. in full sun, solar box cookers look deceptively simple when placed next to some of the other solar cooking equipment. Yet they can cook 10 to 15 pounds of food on a sunny day on semicloudy days, they continue to...

Gas and oil-fired generating plants are drinking up the materials we need as chemical building blocks, for transportation, and for heating our homes &amp offices. Fuels which will be depleted by the turn of the century, less than 11 years away. Coal-fired plants are belching enormous amounts of pollutants into the earth's respiratory system - our atmosphere. Nuclear powered plants pose the threat of meltdown, and are producing radioactive waste by the ton, waste which we cannot dispose of - or...

If it wasn't for your pumps I'd be in big trouble-- no water in the desert. Out here it's NOT an alternative. There's no choice David S., Terlingua, TX My wife and I are just short of ecstatic no longer having to run the goddamn generator 45 min. to 1 hr. a day. M.L., Willits, CA (Slowpump owner) These pumps are really tough. Ours has run for 2 years now. We live some 80 miles from the nearest utility. Jerry M., Alaska (Slowpump owner) Helpers couldn't believe that after they got the old...

The general public currently perceives electric vehicles as poor performers -- slow to accelerate, and limited in speed and range. This belief is based on limited, first-hand experience with pure EVs -ones using only batteries and is, for the most part, accurate. I have rarely experienced an EV, scratch-built or a converted vehicle, that is not sluggish. This turns me off since I find it difficult to ride in, or drive a sluggish vehicle. Accordingly, I find it difficult to advocate the use of...

A schematic of Roger &amp Ana's Renewable Energy System. On the left side of the heavy vertical grey line are 120 or 240 vac circuits. On the right side of the heavy vertical grey line are 12 VDC circuits. The illustration is divided into four levels by the heavy horizontal lines. The top level is Power Sources, the next level down Power Conversion &amp Control, the next Power Storage, and finally Power Consumption. capable of producing 2,000 watts (surge to 6,000 watts) of power that...

However, this low-grade electricity can be channeled into resistive coils (like those found in floor heaters) to continue the braking effect. This is called dynamic braking. The use of dynamic braking minimizes the amount of hydraulic braking required to slow the vehicle. Also, both drum and disc brakes release asbestos dust to the environment as the brakes wear. Dynamic braking decreases asbestos pollution by reducing the rate of brake wear. Your pocketbook...

Automotive electrical system requires 12 VDC for operation. How is this accomplished with a basic 2 VDC lead-acid cell The cells are wired together in series, this makes a battery that has the combined voltages of the cells. A 12 Volt lead-acid battery has six (6) cells, each wired anode to cathode (in series) to produce 12 VDC. Cells are combined in series for a voltage increase or in parallel for an electrical capacity increase. Battery capacity is the amount of energy a battery contains....

(1) INCANDESCENT (the common light bulb) Electric current passes through a thin tungsten metal filament causing it to heat white hot and emit light. The absence of oxygen in the glass bulb prevents rapid oxidation (burning) of the filament. The tungsten evaporates gradually, causing thin spots on the filament (while clouding the glass) leading to reduced efficiency &amp eventual failure. (2) QUARTZ-HALOGEN (also called Quartz-Iodide, Tungsten-Halogen) An improvement on the incandescent bulb,...

The only desirable property we could afford was in the outback. Everything was many miles down a rough dirt road, far from civilized conveniences like electricity. We conquered the bad roads with a 4WD truck and countless hours of mechanical maintenance. The electrical power problem was not so easy to solve. We had to content ourselves with kerosene lighting and using hand tools. The best solution the marketplace could then offer was an engine driven...
